Pharo3 Can not decompile anymore?
by Hilaire Fernandes March 26, 2014

March 26, 2014

Hello, In Pharo3 installation, when I remove both the .source and .changes files (yeah yeah I know), the browser nor the debugger can show me decompiled method code to give me a Smalltalk representation? Is there an option to get it back? Thanks Hilaire -- Dr. Geo http://drgeo.eu

Pavel's CCodeGenerator works under Windows MinGW: sweet
by Philippe Back March 26, 2014

March 26, 2014

I loaded the code from http://www.smalltalkhub.com/#!/~PavelKrivanek/CCodeGenerator where the generator is now standalone, from VMMaker I made my own little version here: http://www.smalltalkhub.com/#!/~philippeback/HOExtras/packages/CCodeGenerato r-Core Just works nicely under windows, not sure for the OSProcess thing as I did the build by hand in a side console. So: CCGExample new nbFib4: <print it> 30 90799453 It just works perfectly. That's a pretty great day for integration with JNIPort and CCodeGenerator!

MethodToolbar plugin for Nautilus
by Philippe Back March 25, 2014

March 25, 2014

I've made a MethodToolbarPlugin for Nautilus. It looks like the old bar from the legacy browser, which I liked to use with the mouse. One can pick the latest package from http://www.smalltalkhub.com/#!/~philippeback/HOExtras/packages/HOExtras-Naut ilus http://www.smalltalkhub.com/#!/~philippeback/HOExtras/versions/HOExtras-Naut ilus-PhilippeBack.13 I'd like to know why the plugin controls aren't honoring the default button heights. It is a general issue for the plugin areas. Ideas? Enjoy, Phil --- Ce courrier Ã©lectronique ne contient aucun virus ou logiciel malveillant parce que la protection avast!

Java "this" against our "thisContext"
by Sergi Reyner March 25, 2014

March 25, 2014

Hi everyone, I had a pretty heated IRC debate yesterday about how SmalltalkÂ´s reflection facilities are superior to those of Java, in the sense that they operate at a higher level (I started it pasting one of those crazy snippets that got posted to the list xD). It somehow slowly degenerated into someone trying to convince me that Java's "this" operator is equivalent to "thisContext", instead of "self". My intuition says thatÂ´s wrong, but IÂ´d very much like someone familiar with both to offer an explanation to this poor unenlightened person :D Cheers, Sergi

neo json and valueSchema for integer attributes ...
by itlists＠schrievkrom.de March 24, 2014

March 24, 2014

I have a class with an instance attribute "x" and this one contains an integer value. No when exporting this to json I want to write a string instead of this number to the json string ... neoJsonMapping: mapper mapper for: self do: [ :mapping | (mapping mapInstVar: #x to: 'x') valueSchema: #AsString. ]. mapper for: #AsString customDo: [ :mapping | mapping encoder: [ :anInteger | x asString ]. mapping decoder: [ :aString | ... ] ]. But whatever I do ... only numbers are written out ... and yes of course I could add additional accessors doing the conversion. -- Marten Feldtmann

question about primitives
by Werner Kassens March 23, 2014

March 23, 2014

Hi, i dont know anything about primitives or the vm, hence this could very well be an extremely stupid question, but anyway: i use pharo 2.0 Latest update: #20628 and (i think) pharo VM version: 3.9-7. (btw how do i look up the vm version?). in the package Collections-Arithmetic there is this method FloatArray>>dot: dot: aFloatVector "Primitive. Return the dot product of the receiver and the argument. Fail if the argument is not of the same size as the receiver." | result | "<primitive:'primitiveFloatArrayDotProduct'>" self size ......bla bla when i change this to: dot: aFloatVector "Primitive. Return the dot product of the receiver and the argument. Fail if the argument is not of the same size as the receiver." | result | <primitive: 'primitiveDotProduct' module: 'FloatArrayPlugin'> "<primitive:'primitiveFloatArrayDotProduct'>" self size ......bla bla it becomes much faster, iow it uses the primitive, and it seems to produce the same results. hence my question, was it perhaps just overlooked, that the primitive has a new name, or what is the reason for not using it? werner

NeoJSON and inheritance
by Norbert Hartl March 22, 2014

March 22, 2014

How is inheritance supposed to work in NeoJSON? I only figured it out by doing that manually: neoJsonMapping: aMapper super neoJsonMapping: aMapper. (aMapper mappingFor: self) mapInstVar: #longitude; mapInstVar: #latitude. Is there a better way to do? Norbert
